Proof step 13 from proof validref-addobj (previous step)

newref(r1, st), r = jvmref ∨ st[r -- _type] .type ≤ ty1 ∧ ¬ junkref(str, r, st) ⊦ r1 = jvmref, validref(str, r, ty1, addobj(r1, class, fis, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ validref(str, jvmref, ty, st)
Proof step 12:
newref(r1, st), st[r -- _type] .type ≤ ty1 ⊦ r1 = jvmref, r = jvmref, validref(str, r, ty1, addobj(r1, class, fis, st)), junkref(str, r, st)
